AGRC1023 Lecture Notes - Lecture 9: Null Hypothesis, Test Statistic, Statistical Hypothesis Testing
Document Summary
This method partitions an experimental variance, allowing to test for differences between the variance due to variance sources. Samples come from population with normal distribution o. One factor, it is a collection of statistical models used to analyse difference between group means and their associated procedures (like variation" among and between groups) Anova model: o o xij = + tj + ij. Individual value (xij) = experimental mean + treatment effect (tj) and residual value ( ij) F ratio (calculated f statistic for the study) F-test is any statistical test where test statistic has f-distribution under null hypothesis. F statistic is value you get when you run an anova test. Observed mean from single sample compared to expected mean of the population mean of the population. Variation in population is estimated based on the variation in the observed sample. Paired sample t-test o o o o o o o o.
